How our little girl is feeling about becoming a big sister.

She's really excited.

She's really protective.

It's been cute.

She's worried about what I'm eating, making sure it's healthy.

She hugs and cuddles the belly.

I mean, it's really been adorable.

You never know how it's gonna go.

And so far she's been so excited.

She tells the entire world everyone every way and just people that check us out of store.

She's like touching on my mom's like we could see clearly.
